ARGAND-LAMP BURNER.

SPECIFICATION forming' part of Letters Patent No. 247,560, dated September 27, 1881.

l Application filed November 22, 1880. (No model.)

To all whom it may concern:

Be it known that I,H 1EAM W. HAYDEN, of VVaterbu'ry, in the county of New Haven and State of Connecticut, have invented an Im- 5 proveinent in Argand-Lamp Burners, of which the following is a specification.

In Letters Patent reissued September 5, 1871, No. 4,541, there is an Argand burner with a at wick bent up into a cylindrical form, and

[o raised or lowered by a metal rack with teeth at the upper end. My present invention relates to the same class of burners, but itis especially intended for burners of a large size.

I make use of a wick-tube the upper portion i 5 vof which is removable to give access to the wick, and theiwick-raising rack is applied between the edges ot' the wick and is connected to a ring with teeth around the air-tube. The wick is properly placed by hand and pressed zo upon the teeth ofthe ring, after which the removable section of the wick-tube is replaced. The cone that directs the air to the base of the iarne is made with an internal hanging ange that forms the proper guide to direct the air,

and at the same time allows the body of the cone to be farther removed from the heat of the ame, and causes the ascending current of airl to impinge upon the metal in such a way as to reduce the temperature of the burner. l also 3o make use of a deflecting-button and a movable extinguishing-tube, that, when raised by a cam, comesintocontact with the button and simultaneously extinguishes thelight and confines any gases and vapors, so as to lessen the disagreeable smell when the light is put out. There is a supplemental air-distributer within the cone, that serves to proportion the drafts that pass to the name, as hereinafter set forth.

In the drawings, Figure 1 is a vertical section of the burner complete. Fig. 2 is a plan of the same, with the chimney-holder, dellector, ai'r-distributer, upper part of the wick-tube, and extinguisherbutton removed. Fig. 3 is an elevation of the burner with the chimneyholder and cone removed; and Fig. 4 is a section ofthe removable portion of the wick-tube and the extinguisher-tube. Fig. 5 is a section `at the line :c w ofFig. 1.

The air-tube a. is closed at the bottom end 5o by the plate a. Within the air-tube is a separate tube, a', with wings 2, the objectof which is to insure the vertical movement of the air Within thetube a. This tube may also have vertical slotsin it, as at o3, and one wing may extend down to the plate a2, to support the tube a. There is also arod, b, attached at the bottom of the air-tube, and carrying at its upper end the button c.

The metal ofthe air-tube, near the lower end, is slit upwardly a sufficient distance to form 6o the lateral air-inlet by bending the metal outwardly a sufficient distance to reach the wicktube d, in which wick-tube there is an opening, and the plate a2 forms the bottom of thislateral l air-inlet, and there is a plate between the airtube t and wick-tube d to form the top ot' the air-inlet. The parts are soldered or otherwise attached together.

The burner-screw c and the gallery f are both attached to the lower end of the wicktube d. 7o

The wick-raiser is made of a band, t', around the air-tube a, having outwardly-projecting teeth, and to this band t' the rack o is perma nently fastened.

Through the metal forming the top and bottom of the lateral air-inlet there are openings, and the rack o passes through these openings and slides in and is guided by these portions ofthe burner. By this construction the rack 0 is at that portion of the burner where the 8o lateral air-inlet is provided for the central airtube; hence said rack is between the edges of the at wick when entered in abent condition into the burner, and this also allows the wickraising wheel 7L to be introduced within this 85 lateral air-inlet to act by its teeth in the row of holes in the rack, and raise or lower the same and the wick-raising ring t'.

The axis of the wick-raising wheelh is supported at one end in the bracket 3, and near 9o thebutton-head bythe galleryf,through which said axis passes.

The upper portion, 7c, of the wick-tube is movable. It screws into the lower portion of the Wick-tube; -hence when the part 7c is re- 95 moved the wick is exposed, and can be applied properly upon the teeth of the band fi, and the screwing on of the portion lc holds the wick to the teeth.

The upper end of the wick-tube is slightly roo contracted, so as to setclosely around the wick, and around the said wiclctube 7c there is the supplemental air-distributer l, formed of a perforated ring, which serves to steady the current of air that ascends outside the wick-tube, and this air-distributer also steadies the removable cone and chimney-holder.

The extinguisher is formed of a tube,'m, surrounding the wick-tube and slidin gfreely thereon. There is a leg, 6, that is attached to the tube m and passes downwardly through the guide-slide 7 upon the air-distributer Z; and there is a cam-shaped arm, o', that projects from a short rock-shaft, 8, having its bearings at the gallery f and in the support 18, and a crank-handle, 9, or button outside the gallery, by means of which the cam is moved to act against the bottom end of the leg 6 and raise that and the extinguishing tube or sleeve m until the upper end comes against the button, as shown by dotted lines in Fig. 3, so as to effectually stop the currents of air and cause the iiame to be ixtinguished. At the same time the gases or vapors that are so objectionable when a lamp is blown ont are confined so long as the extinguisher iskept up against the button.

Vhen the cam-arm is liberated it and the eX- tinguisher fall by gravity.

rlhe cylinder s rests upon the gallery, and the lower part is perforated at l0 to form an air-distributer, and the upper part is slotted to form a spring chi1nney-holder, 1.2.

The cone or dedector t is attached at its base to the cylinder s, and it is perforated at 13 to allow air to pass outside the detleetor and withinthe chimney. rlhe upper end of this deflector is contracted and formed with an internal hanging iiange, u, against which the ascending currents ot' air impinge, and thereby keep the cone ordetiector cool, and this hanging flange, being nearly cylindrical, forms a guide to direct the air vertically upon the base ofthe dame.

I am aware that a lamp has been made with a removable section to the wick-tube and with a wick-raising ring having teeth on the top edge, as in English Patent No. 3,104 ot' 1862. 1n this case there is difficulty in introducing the wick, and in causing the points to penetrate the same, because the wick has to be passed down inside of thering, and then spread outwardly and pressed down upon the points. By my improvement the wick, being outside ot' the wick-raising ring, can be opened and moved up or down and simply pressed against the projecting points of the ring when the wick is in the proper position, thus greatly facilitating the adjustment ofthe wick.

I claim as my invention- 1. In an Argand-lamp burner, the wick-raising ring having outwardly-projecting teeth, and slidiu g upon the wick-tube, in combination with the rack passing downwardly across the lateral air-inlet tothe air-tube, and the ratchetwheel placed in said air-inlet, substantially as set forth.

2. The combination, in an Argand-lamp burner, of an air-tube closed at the bottom, a wick-tube around the air-tube with an intermediate space for a fiat wick bent to a cylindrical form, a lateral air-inlet, a wick-raising ring having outwardly-projecting teeth and sliding on the air-tube, means for moving the wick-raisin g ring, and a removable section at the upper part of the wick-tube, substantially as set forth.

3. The supplemental air-distributer l, in combination with the wick-tube,airtube, removable chimney-holder, air-distributer, and deilectorot' an Argand burner, such supplemental air-distributer surrounding the wick-tube at the base of the detleotor, and serving also to steady the removable portions of the burner, as set forth.

et. Thecombiuatiomwith theArgand burner having a button, of a sliding extinguishersleeve surrounding the wick-tube, and means for raising the extinguisher to the button,sub stantially as set forth.

5. The eXtinguishensleevem, havingadownwardly-projecting leg, 6, in combination with the wick-tube, the supplemental air-distributer l, through which the leg of the extinguisher' passes, and the cam-arm o and its actuating 95 shaft, substantially as set forth.

6. Thecombination inan Argand-lamp burner, of an air-tube, a wick-tube having a removable section, a wick-raiser around the airtube, and means for actuating the same,a slidroo ing extinguisher-sleeve around the wick-tube, and means for moving such extinguisher,sub stantially as set forth.

7. In combination withlthe air and wick tubes in an Argand burner, a deiiector surrounding 105 and near the top of the Argand wick, and having a vertically-hangingcylindrical fiange within its upper end, for the purposes and as set forth.

8. The combination, in an Argand lamp, ot' 11o a deliector having a hanging flange at its upper end and holes near the base of the deiiector, a chimney-holder, and air-distributer formed ot' a cylinder around the deflector, and a supplemental air-distributer within the base 1 15 ofthe detlector, substantially as set forth.
